Product Introduction

ADM-2511 is a product designed to solve the problems of weak signal and easy signal interference during long-distance transmission of RS-485/422 signals. Can extend RS-485/422Increase the communication distance of the bus and increase RS-485/422The number of devices in the network supports a maximum transmission rate of 115.2Kbps. The RS-485 interface uses optoelectronic isolation technology and a 600W lightning surge protection circuit, providing an isolation voltage of 1500V to effectively suppress lightning and ESD protection. The discrimination circuit used in the RS-485 working mode can automatically sense the direction of data flow and automatically switch to enable the control circuit, easily solving the problem of RS-485 transceiver conversion delay. The RS-485 interface has a transmission distance greater than 1000 meters and stable performance. Widely used in highway toll collection systems, road monitoring systems, and power collection systems, it is a high-performance and cost-effective data interface conversion product.
